Finally...

one I am pleased with.  I know that there is no shading for form, but I took the time to really observe and render with a bit of care and, at least for the rest of the evening, I turned a corner.  With a little focus I was able to finally put myself in a zone.  This is not to say I don't focus on my work, I do.  However I was able to block out the clock and everything else and just make my hand place the lines where I wanted them to go, with the subtlety and weight that I wanted.  This led to the final three drawings of the night that made me feel pretty good.  Of course, the key is to stay in the zone...
